Adjustable Coil Bolt consists of a length of Coil Rod with a Coil Nut welded on one end and a free-running Coil Nut on the other end The allows formwork adjustments to be made with the free-running nut and can accommodate various form thickness as with one size adjustable bolt. This is especially useful in forming battered walls.
Adjustable Coil Bolts are designed to be reusable, but they do wear and must be continuously inspected and replaced when wear or damage is noted. A waterproof grease should be applied to the portion of bolt that will be embedded in the concrete. This will facilitate bolt removal from the set concrete.The safe working load of the bolt is limited by the safe working load of the welded coil nut head.
